| Outcome this study informs | Pooled effect | Evidence | Certainty |
|---|---|---|---|
Inter-second deciduous molar distance (ISDM) transverse change Slow maxillary expansion (SME) with spring-based Leaf Expander vs Rapid maxillary expansion (RME) with conventional Hyrax- or Haas-type expander · Change from baseline (T0) to post-treatment (T1), at completion of active expansion | SMD 0.19 [-1.47, 1.86] | 2 studies | Very low |
Inter-first permanent molar distance (IFPM) transverse change Slow maxillary expansion (SME) with spring-based Leaf Expander vs Rapid maxillary expansion (RME) with conventional Hyrax- or Haas-type expander · Change from baseline (T0) to post-treatment (T1), at completion of active expansion | SMD -0.17 [-0.56, 0.21] | 3 studies | Very low |
Inter-canine distance (IDC) transverse change Slow maxillary expansion (SME) with spring-based Leaf Expander vs Rapid maxillary expansion (RME) with conventional Hyrax- or Haas-type expander · Change from baseline (T0) to post-treatment (T1), at completion of active expansion | SMD 0.13 [-1.24, 1.50] | 2 studies | Low |
